At the end of the SWAP I'm assuming the MVS I/O is re-directed
to the SWAP Target and it is brought Online.
Correct
At that point do we have two volumes with the same label?
If we IPL then what do we see?
As I said, we modify the label on the source volume so that it can't be
brought online, so IPL will ignore it and only see the volume on the
target disk.
And I wonder what XRC sees during the SWAP with the Target offline,
but since XRC is controller based it should see all of the I/O traffic from
FDRPAS.
If you have established a XRC session on the FDRPAS target disk prior to
the swap, then all the WRITEs to that disk should be mirrored,so the XRC
secondary will be an accurate mirror of the FDRPAS target disk when it
is brought online.
FDRPAS does no WRITEs to the source disk except for modifying the volume
label at the end, so that change should also be mirrored by that XRC
session.
